Ships don’t sink because they are big and strong, just like floating toys in your bathtub! 🛁✨ They are designed to stay on top of the water.
Inside a ship, there is a lot of air, which helps it float. The shape of the ship is also very important—it spreads out wide to stay balanced on the water.
Ships stay afloat because of a scientific principle called buoyancy. 🌊 The water pushes up on the ship with a force equal to the weight of the water it displaces (pushes aside).
The ship’s hull (body) is hollow and filled with air, making it less dense than water. This means it floats! Engineers also design ships to be wide and stable, so they don’t tip over.
Ships float due to Archimedes’ Principle, which states that the buoyant force (upward push) on an object in water equals the weight of the water it displaces. ⚖️
The hull is designed to displace enough water to counteract the ship’s weight. Even though ships are heavy, their large volume spreads the weight over a wide area, keeping the overall density lower than water.
Modern ships also have watertight compartments—if one leaks, the others keep the ship afloat. This is why the Titanic sank—its compartments weren’t sealed properly!
